Determining the quality of products such as movies, games is not elementary, because such cases are decided in court.

To determine the quality of such products is elementary. For example, for the film:

1st Entrance to the hall is free.
2nd He entered the hall before the advertisement - received a hundred rubles.
Three The first half hour of the movie is free of charge.
4 is Exit from the hall after the end of the film is 500 rubles.
5 is Leaving the room after the first half an hour is proportional to how much time remains until the end of the film.

This is just something that suggests me that as a result of the cult filmmakers will learn a lot about themselves.
